STREET-CAR H EATER.

SPECIFICATION forming part of Letters Patent No. 353,108, dated November23, 1886.

Application filed December 19, 1885. Serial No. 186,199. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE VVISEMAN, of Lawrence, in the county ofDouglas and State of Kansas, have invented a new and Improved Street-OarHeater, of which the following is a full, clear, and eXact description.

My invention consists in the construction and arrangement of parts, aswill be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings,forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a longitudinal, vertical, sectional view of a streetcarprovided with my improved form of heater. Fig. 2 is a perspective viewof the heater removed from the car. a cross-sectional view of theheateron the line a: m of Fig. .t. Fig. 4 is a longitudinal sectionalview of the same on line 3 3 of Fig. 3. Fig. 5 is a plan view of aportion of one of the platforms. Fig. 6 is a horizontal sectional viewon the line 2 z of Fig. 3.

Referring now to the general construction illustrated in the drawings, Arepresents the flooring of the ear, and B B the platforms of the same,beneath which platforms there are secured the heaters C. These heatersconsist of a cast-iron arch, D, the ends of which are closed byrectangular front and rear castings,

as E and F, which serve as supports for the grate G and for the ash-panH, which is sus- In the end piece E there is the usualfire-door, I,which door is mounted so as to swing outward and downward, theconnection between the door and plate being made at the two lowercorners of the door, as clearly shown in Fig. 2. In the main door Ithere is a peep'hole, a. The end piece F is provided with a flange, b,to whichthe stove-pipe J is attached. The archshaped fire-box D iscovered by a double-wallbox-like structure, K, which is fitted tightlyagainst each of the end castings, thus forming the airchaniber L abovethe furnace D. The furnaces Gare secured beneaththe platforms B, asshown in Fig. 1, connection being made by means of bolts which passthrough apertures formed in lugs c c, which project from castings E andF. The cold air to be heated is led into the chamber L through a flue,M, which leads up Fig. 3 is thrown by the horses.

through an opening formed in the flooring of the car, and in order thatthe entering air may be deflected and caused to pass over the surface ofthe furnace I place a semicircular deflecting plate, N, within thechamber L. After the air has been heated it passes out of thechamberLthrough an opening, 01, which leads intoadistributing-chamber,0, from which the hot-air fiues branch out.

Each furnace is preferably provided with three hot-air delivery-fines,as P, Q, and R, the flue P leading to a register, 6, in the platform,while the fines Qand Rlead to registers f and g in the flooring of thecar, the two flues Q and B being divided by a longitudinal partition,'h.

In order that the hot air passing through the dues may not be tooquickly cooled, I prefer to form the fines with double walls, as t 12,so

that each will be surrounded by an air-space.

the horses feet I arrange a heavy piece of sheet metal in front of eachfurnace, thus forming an apron which will intercept any matter A Theseaprons T are hinged to the platform at If, so that they may be folded upagainst the dash-boards U, in which position they will be held bycatches it.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A street-car heater comprising the casting D, its end plates-E F, thegrate supported by said end plates, the doublerwall air-chambersupported by the casting, the horizontal pipe d, leading to the outsideof the'air-chamber, the horizontal double-wall distributingchamber 0,communicating with said pipe d, the separate and independent horizontalregister-pipes P Q R, leading from the ends of the distributing-chamber,the air-supply pipe M, leading from above the heater down to the lowerpart of the air-chamber, and the smoke outlet J, substantially assetforth.

3. The combination, with the car having a register in its platform, ofthe swinging protectorM, forming a space to receive the driver over theregister, substantially as set forth.

THEODORE WISEMAN.
